Color: Black Size: Free [Product Description] We have selected a thick flight cap and attached snap buttons. It looks great when worn under a half-helmet type shorty or jet helmet. A must-have item for vintage, wartime, and military enthusiasts. It has snap buttons (female side) so it can be worn with shorty helmets and other helmets. The thread is sturdy and uses waxed thread that is resistant to fraying. [Notes] * We have checked the attachment and detachment of all snap buttons. Sometimes the snap buttons fit tightly and are difficult to remove. In that case, do not pull the fabric, and use a flathead screwdriver to remove the button without putting stress on it. We inspect all buttons before shipping, so we cannot exchange them due to snap button damage. Please understand this before purchasing. * When attaching the snap buttons, we have removed the threads from the original sewn areas, so there are small holes as shown in the image. * The button crimping may be strong, and the sewing thread color may change slightly. If you are concerned, please refrain from purchasing. * Helmet is not included. * When using with a helmet, removing the inner pad allows for a deeper fit.
